Questions & Answers

Compressor has a 2 stage sound when it starts. Over the last year the 1st stage starts and takes 20 minutes to build air. I do not hear the 2nd stage come on. What needs repaired?
Ronald L Dennis for model number OF45150A asked on 2019-08-14
Hi Ronald, there could be a variety of causes however Id check a few things 1. Broken inlet valves 2. Intake filter dirty 3. Connections leaking Thank you for your question and good luck with your repair!
The compressor works fine when pumps until it reaches max pressure. When it stops it leaks air from the bottom of the pressure switch. Seems like it's coming from the unloader. The pressure switch is new. The old one was doing the same thing.
Gabor for model number OF45150A asked on 2019-06-23
Hello Garbor, looks likely your unloader is giving you this trouble. Part number 17883. Hope this helps

Hi my ridgid compressor does run but does not build any presure
Arturo for model number Of45150A asked on 2020-02-11
Hello Arturo, thank you for your question. We would recommend replacing these parts to fix that issue. Valve Plate Kit Part#: 17983, Discharge Valve Gasket Part#: 17978, Head Gasket Part#: 17973 and Cylinder Gasket Part#: 17958. I hope this helps.
Compressor starts, builds 150 PSI but whdn the pressure drops from usage it just hums loudly and trips a 20 amp breaker. What's the best guess here?
John for model number 45150A asked on 2020-02-19
Hi John, thank you for your question. There are two parts to generally check when you are having this issue. The first would be your check valve, you may also need to check the pressure switch as well. Good luck with your repair.

Question: Rigid Air Compressor

1346626

The groove on the head gasket, which way does it install, ridge up or down?
Hi,
If I remember right there is a pin that only allows it to be installed one way.Check to see if that's the case.

Question: RIGID AIR COMPRESSOR Model OF451...

1246796

I have a Rigid Air Compressor Model # OF45150A.
How do you get the balancer off the front of the motor? The front bearing has gone out.
Does it screw off or does it have to be pressed off?
Thanks.
Hi ,
You don't want to take the balancer off the motor.You will need a bearing splitter to remove the bearing.Hope that helps.Good luck.
